I have patches in progress that fixes cross-debugging endian
problems (currently it copies target addresses bitwise and
compares it to endian-adjusted data), completely missing
DWARF2_REG_TO_REGNUM mapping and a bug that sets the PC for all
frames as the last frame. Those issues might be what's referred
to. More about that in a day or two.
I have no way to test them (no x86-64 here) other than a
port-in-progress. Suggestions how to test dwarf2cfi.[hc]
changes welcome.
Maybe I should mention that I *really like* the presence of
dwarf2-interpreting machinery. Takes a lot of work on frame
stuff away for a port. Thanks!
brgds, H-P
